Problems solved by technology

However, in this example, the absence of these new fields is due to the fact that the target eNB does not understand those fields, and the target eNB explicitly does not support later release protocol features
Therefore, a mismatch can occur, where the UE continues to use functionality not implemented by the target eNB, and since the communicating peer entities (UE and target eNB) will be configured differently, serious protocol and functional errors can occur

Abstract

Methods and apparatus in a base station and user equipment are provided. Methods and apparatus relate to situations when a UE is handed over from a source base station to a target base station in a handover situation, and wherein the target base station may not support functionality supported by the source base station and the UE. The method in the UE comprises receiving (501) a configuration message from a target base station via a source base station, configuring (502) based on the received configuration message from the target base station by searching (503) a second field in an information element of the received configuration message UE. The presence / absence or value of the second field indicates how the configured first functionality associated with the optional first field is managed, wherein the target base station may not support the configured first functionality.

Description

technical field [0001] The present invention relates to methods and arrangements in telecommunication systems, in particular to methods and arrangements for use in networks comprising base stations, wherein the base stations may have different radio resource control capabilities. Background technique [0002] The Radio Resource Control (RRC) protocol in 3GPP Long Term Evolution (LTE), also known as Evolved UTRAN (E-UTRAN), is a signal used to configure and reconfigure the radio interface configuration of a User Equipment (UE), also known as a mobile terminal. command agreement. This protocol is disclosed in the technical specification document 3GPP TS 36.331. [0003] The first release of RRC for LTE (described in 3GPP TS 36.331), Rel-8, deploys a solution where fields in Information Elements (IEs) can be omitted from messages. IE consists of fields. Each field includes separate content or another IE which in turn includes fields or further IEs. In addition, a message in...
